I'm planning to build two Punishers to complement some existing PA cabs
I've got. Having had a look through the plans, building them shouldn't be a problem. However when it comes to crossovers whats the best way forward? I want to be able to still use my existing cabs as full range units for smaller indoor jobs, and use the punishers on larger jobs or outdoor ones. How would you do it? Also where do you guys put handles on your punishers! >.< and would I be foolish to only have 2 castors and try and go for a parcel truck way of movement!? Any recommendations for amplifiers to drive them with? I'm just about to buy some more amps anyway for the other cabinets, was thinking QSC PLX range, to replace the 20 year old Studiomaster brute driving them at the moment! Thanks in advance! Laurence |

Infinate 8's do look very nice, But I'm sadly not going to be able to afford
them after I've built the subs! :( I was thinking £450 tops for an amp.... I assume I could run the amp in bridged mono mode, with the two subs connected together creating a 4 ohm load? What do people think of.... QSC MX1500A http://www.allprosound.com/catalog/pdf/specpdf/QSC/mx/ MX1500a.pdf Crown PT 3.1 http://www.crownaudio.com/pdf/amps/133377.pdf Or anything else for that matter! I assume I will have to get an active crossover to compensate for the delay between the drivers, and the horn. Laurence |

QSC MX amps are good.. but... go with the higher series.. ------------- .:Uprising Sounds:. |

I wish I could afford a more powerful MX :(
Moneys tight with building the two punishers.... The specs of the Crown are... 525 8ohm per Channel 1530 8ohm briged Mono I'm a little confused about the differences of Bridged Parrell and Bridged Mono? After spending aages googling I'm still unsure! >.< any hints! I figure if I connect the two Punishers in parrell, and run the amp bridged? Laurence p.s Thank you!!! |

Okay maybe I've found a little more money ;)
I'm going to look at the PLX's a bit more carefully, I've used them before on a few goods and they seem pretty good. Might have a C-Audio RA2000 as well by the end of next week. I figure I'll go with the el-cheapo Berhringer crossover initially, and upgrade latter this year to somthing decent like the BSS. 4 Castors on each unit. Top of the end PLX to drive them, running bridged mono with the speakers connected in Paralel. Ordering the wood tommorow (russian birch 15mm @ £29 a sheet) Would you rebate the joints? The plans don't have any rebates only mitre's. Ta for the advice so far. LG |

Hello, The plans are drawn in such a way that even relative unexperienced woodworkers can build a Punisher. If you can do better joints please do, the stronger te cabinet the better. Also make sure there are no airleaks. QSC PLX seems very good value for the money. But I did not hear these amps on Punishers so cannot commend on how well this works. Best regards, Walt |

The MX line is nothing but the current HD series .. take that into consideration... also a dual monoraul supply is better on Subs..
the plx is good..but id go with a torrodial amp.. like say a Crest or something different for those low notes.. no *lag or feel as the amp cant supply that punch* ------------- .:Uprising Sounds:. |

I'll have a scout about, £500-£550 is really my upper limit!
Its really gotta be suitable to drive the studio monitors as well, and leave some money for the crossover. I'll see if I can do any more elaborate joints, my wood supplier only does ply in 1525mm x 1525mm sheets, so you get 1 punisher from 2 sheets, but there's not much spare. I had thought of maybe drilling&screw as well as glue the side sections, but on reflextion I'm not sure how well the ply will take it, being screwed into side on. I'll have a think about the joints while I'm waiting for the wood to arrive! Cheers for the advice... Laurence ( Oh, one last thing is there any sonic difference in which orrientation the cabinet is used? I.e upright or on its side? I've just measured up the relfex RCF cab's I'm planning to stack on top, and it looks like I'm going to have to lay the punishers on there sides. ) |

| what about the t.amps from thomman? |

Need to be relativly good qaulity, as when I buy a few more/somthing better it will replace the Hafler Ta1600 in the studio. Those TBone amps are very cheap tho! Wonder what they are really like. Laurence |

Right picked up a QSC PLX3002, which is capable of kicking out 3,000rms
bridged, so its just about enough for those punishers. The plan is to pick up another one, once we get some money in. Just ordered all the cable, sockets, etc I'm gonna need, scary how much it racks up to, £150 of my hard earned cash disappeared! :( I've been busy this week, so I've gotta finish marking the plans out, and send off the paint colour sample to be mix. Then its all systems go, I've got a professional carpenter on-board now. If all goes well, and once we've built a few mone. We are thinking about maybe building some units to sell, if anyone is interested? I'm quite interested in the Xtro as well... What else would make a suitable top? I'm going to run my RCF units on top for the time being. We are also planning to build 2 lab horns. Will be interesting to see how they compare, and combine. Laurence |

Checked out the wood today, its lovely! :)
I'm going to go into the workshop tommorow, and mark it all out. Any tips? Then we will machine the wood on Thursday, and start building on Friday, and hopefully finish next week. Still not sure about these access panels, some advice on how they are fitted, and how the removable bits are removable would be apperciated. I've got quite lucky recently, so a pair of Xtro's may be on the cards! ;) Laurence |

Whats the best order for assembley?
I assume you build the horn and speaker mount section first, but do you work out, or in? Laurece |

If you need a 2nd amp, I know of a decent one cheap. Yamaha P7000S which gives 3200w rms into 4 ohm bridge. And found it here 2nd hand for £350. http://www.rockfactory.co.uk/proddetail.php?prod=ppa-yama001 - http://www.rockfactory.co.uk/proddetail.php?prod=ppa-yama001 It's also a switching amp.

Right all the wood is now cut! Cut the last panels today, the ones the speakers are bolted onto... However I'm not happy with the tollerance I've achieved, and it seems a bit tight. So I'm off to get some new wood, and do those again! Once there cut tommorow morning, we're gonna start assembling! - I figured it would be easier to cut the access panels after I'd made the horn speaker section, so I'd know exact dimensions, and it would all line up.

| Using different amps in the same frequency range isn't recommended. |

Units are built...
Just did the sound for a large party in some field with them, worked very well. Well impressed! |

Hello,
Can you give some more info about this party? How many Punishers, amplifiers, people?
Best regards,

2 punishers, with our RCF Tops.
Punishers running off a QSC PLX3002, RCF's off the old Studiomaster 1600C. Using a DCX2496 crossover. (40hz and 100hz) No idea how many people there where, we where setup in a marque running more ambient alternative stuff from 8pm - 10pm, slowly moving across to move commercial dance till around 1pm, and then shifting to dub/more interesting stuff till 5am. Probally at its peak around 400 people, so pretty small compared to some of stuff you guys do! But for myself thats quite a big crowd! The minute I fired up the system with my soundcheck CD (Ian Dury - New Boots and Panties) I knew we where gonna have to build some more punishers! Lovely bass bins! Was worried at first the drivers where gonna overheat, not really sure why? But I was worreid! >.< but no problems at all... Running solid from 8pm till 5am. Thank you for the design! Its very impressive! Really wish I'd taken some photographs that night! Laurence |

Yes, me too thinks they work pretty well from 40 to 100Hz, even if I never heard them with the Ciare speakers in them.
@ Walt: It would be nice if you'd answer my PM or at least reply 'Sorry, I won't answer'....

Hello JD, There were made some attempts on a dutch forum on a wider punisher (600mm) but it turned out that if one would keep the cabinet volume the same, the hornpathway becomes very narrow at the start of the horn. If you would just take the original Punisher design and widen it to 588mm this will work. Tell me which driver you want to use and I can run some simulations to see if it is worth the effort. But I think there are very little 12" drivers which have the output capability of the Ciare. Also for pgwle, 400 people is quite a lot, I would use 4 Punishers for such a crowd.
Best regards,
Walt |

I will use the 12.00SWdc, as the normal 12.00SW is a bit hard to get, as they aren't on the distributors stock.
I want to take the original desing and just widen it to 588mm. Most simple way would be to just widen the part before the first fold, so it starts like on the original design at the speaker cutout but ends on 552mm width.

I've considered replacing my wood wide panels (25mm rebate) with some metal panels.
However I was wondering how this would affect the structural integrity of the cabinet, as it would be a different material, different resonce, etc. I could easily machine a texture aluminium panel, which would give a slightly higher surface area, and would help radiate heat from the chamber.

i was also wondering about the heat disipation in the PII's
microchamber (plus they look tasty on the labs!), also i can't seem to
find that post about the benefit in lagging the chamber or hornpath, or
was that elsewhere? |

| PGWLE: Were you giving the Punishers the full 1500W each? How did your mid tops cope with them? I thought the RCFs were only rated at aout 300W each... |
